Wait a minute... where did the 100F figure come from ?
In your original post you state you want to store wind generated electricity. One of the responses showed that it would take a 100 F capacitor to store enough energy to light a 100 W bulb for 1 hour.
You guys are off by more than an order of magnitude. A 100F capacitor charged to 120 volts would light a 100 watt light bulb for only two minutes, not an hour. You need a 3000F capacitor to get an hour.
That is, of course, assuming that your (Batteroo-Brand?) boost converter can slurp
all the energy from the capacitor, over an input voltage range of 0 to 120 volts, with 100% efficiency.
A 3000F parallel-plate capacitor with a .001 inch plate spacing, aluminum oxide dielectric (dielectric constant of 8.4) requires about 400 square miles of aluminum foil. Even once you double the effective surface area by rolling it up to use both sides of the plates (200 square miles) and increase the surface area by roughing the surface, I don't see how this idea is even remotely feasible, no matter how close you might be able to make the plate spacing.
You need electrochemical cells or pumped storage or something to even begin to be in the realm of being possible. Even thinking about being able to store that amount of energy in an electrostatic field is pure insanity!
